This is a rare "Betty Boop" Silver strike, from the 4 Queens casino in las Vegas. Since you can't win this one anymore, I hope to buy one from a dealer or at auction, like eBay. I have been fascinated by these coins, and they are a disappearing piece of old las Vegas. The 4 Queens casino still has several Silver Strike machines, and makes special series of these unique $10 tokens available. I know it is not crypto, but really cool.
